[UBUNTU:sound/pci/] Add hp_only quirk for pci id [161f:2032] to via82xx ALSA driver

http://www.kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-dapper.git;a=commitdiff;h=eae2cc78de39502595f67b7fc1f821f5963bb8ae

UpstreamStatus: Not merged

Christian Bjalevik reports in LP#38546 that his sound chipset requires
the "hp_only" quirk to allow him to control sound volume correctly when
headphones are inserted. This patch adds the appropriate pci id to the
via82xx ALSA driver so that the quirk is applied automatically, thereby
removing the need for users to modify /etc/modprobe.d/alsa-base (or to
unload and reload snd-via82xx with ac97_quirk=hp_only).

This patch closes LP#38546.
